Privacy Policy

    Last updated: March 13, 2026

    1. Information We Collect

    NappyTi.me is designed to respect your privacy. We collect minimal data to provide our sleep calculator and ambient sound services:

    • Local Storage Data: Your sleep preferences (wake time, age group, sleep cycle length, fall-asleep time) are stored locally on your device using browser localStorage. This data never leaves your device and is not transmitted to our servers.
    • Usage Analytics: We may use privacy-respecting analytics to understand how visitors interact with our site. This data is aggregated and cannot identify individual users.
    • Cookies: Third-party advertising partners (such as Google AdSense) may use cookies to serve personalized ads. You can manage cookie preferences through your browser settings.

    2. How We Use Your Information

    We use the limited information we collect to:

    • Save your sleep preferences locally so you don't have to re-enter them each visit
    • Improve our sleep calculator algorithms and user experience
    • Display relevant advertisements through Google AdSense to support the free service
    • Understand aggregate usage patterns to prioritize new features

    3. Third-Party Services

    NappyTi.me integrates the following third-party services:

    • Google AdSense: Displays advertisements on our site. Google may use cookies and web beacons to serve ads based on your browsing history. You can opt out of personalized advertising at Google Ads Settings.
    • Google Fonts: We load fonts from Google's CDN to ensure consistent typography. Google's privacy policy applies to this service.

    4. Data Security

    Since we don't collect personal data on our servers, there is minimal risk of data breaches affecting your personal information. All sleep preferences are stored exclusively in your browser's localStorage. Clearing your browser data will remove all stored preferences.

    5. Children's Privacy

    NappyTi.me is a general-audience tool. We do not knowingly collect personal information from children under 13. Our age group selector (baby, toddler, child, teen, adult, senior) is used solely to adjust sleep cycle recommendations and is stored only on the user's device.

    6. Your Rights

    You have the right to:

    • Clear all locally stored preferences by clearing your browser data
    • Opt out of personalized advertising through your browser or Google settings
    • Use browser extensions to block third-party cookies and trackers
    • Contact us with any privacy concerns

    7. Changes to This Policy

    We may update this privacy policy from time to time. Changes will be posted on this page with an updated revision date. Continued use of NappyTi.me after changes constitutes acceptance of the revised policy.
